DENSITY GRADIENT CENTRIFUGATIONS Meaning and
Definition
-
Density gradient centrifugation is a technique used in biochemistry and molecular biology to separate macromolecules, such as proteins, nucleic acids, or organelles, based on their density differences. It involves the creation of a density gradient within a centrifuge tube, where a sample solution is layered on top of the gradient. When the tube is centrifuged at high speeds, the particles within the sample move through the gradient, with each particle settling at a specific position depending on its density.
The density gradient is typically composed of a solution with increasing density from the top to the bottom of the tube, for example, a sucrose or cesium chloride solution. As the tube spins, the particles within the sample sediment through the gradient until they reach a region where their density matches the surrounding density. This results in the formation of distinct bands or fractions in the centrifuge tube, with each band containing particles of similar density.
Density gradient centrifugation is a versatile technique that allows for the separation and purification of different macromolecules or organelles with high resolution. It is commonly used in the isolation of subcellular organelles or viruses, as well as in the purification of specific proteins or nucleic acids. By controlling the density of the gradient, researchers can manipulate the rate and position at which different particles move, enabling the extraction of specific molecules based on their density characteristics.
